Once again, I don't get it....on all of these machines, none of this
should be necessary.  Under NetBSD, if you have a softpower machine (i.e.
a II-series Mac or the tower Quadras, I believe), when you do a 
'shutdown -h now' it should powerdown the machine.  It certainly does so
on my machine.  On non-softpower Mac's (i.e. the Classic style Mac's,
LC's, and pizza-box Quadra's), NetBSD _will_ put up a notice that it is
safe to switch off the machine.

If you're machine(s) is/are not doing this, then you've found a bug
(albeit, a somewhat known one).  Please send a PR about it.  However, it
is safe to manually power off a machine even if it has hung during a
'shutdown -h' as long as the disks have finished syncing.  If the disks do
not sync, it might be better to reboot, run fsck, do a 'reboot -n', and
then shutdown from the MacOS.

I hope this clears things up some.

Later.
